Strange problem you've got, Nitecom.
I recently played and won my first game with a Super Annihilator race. I got the technologies of Toxic Atmosphere Reductor and Advanced Toxic Atmosphere Reductor automatically when I researched Spore Weapons(and this took only 3 weeks). Throughout the game, I ran my many spore-intoxicated worlds at max production with no problem, and occasionally traded my Reductor techs for surprisingly large amounts of money to the AI.
Later in the game, I flipped an Aquatic world, Dark Yor 2, over from the Korx, and it did absolutely nothing. No production, nil. Only 2 research points, with focus on research having no effect. Then, even later in the game, I stole Aquatic World Colonization while I was spore-bombing the planet Korx. Now Dark Yor 2 was running at half-strength, just as it was supposed to.
The only mod I had was Kryo's Hull System.
BTW, I never had Extreme Colonization at any time in the game.
And how did it take you 70 weeks to research the techs? Try focusing your worlds to research and turning the slider up to see that time figure tumble down like crazy. If it doesn't, your researching capability is just plain weak.
